Sony CDU31A/CDU33A device driver for the Windows NT(tm) operating system ------------------------------------------------------------------------ NOTE:Please make sure to prepare a blank formatted disk, then copy all files under sub directory "WIN_NT" to the root directory of newly formatted disk for easier installation. The device drivers and this file are owned by Sony and protected by United States copyright laws, international treaty provisions, and all other applicable national laws. You may not reverse engineer, decompile, or disassemble the device drivers. Copy all files from this directory to the root directory of a floppy disk and mark it 'Sony - CDU31A/CDU33A setup disk'. Installing from a CDU31A/CDU33A - x86 processor ----------------------------------------------- To install Windows NT from a CDU31A/CDU33A drive with no other supported SCSI host adapter installed, boot the computer from the Boot floppy provided with the operating system. After you hit ENTER to indicate 'install now' and then choose Custom install, the installation software searches for a supported host adapter and CD-ROM drive. It displays 'Scanning for SCSI adapters' in the bottom of the screen. The device drivers used during this phase of installation are expected to be on the Windows NT CD-ROM disc, which these currently are not. When the scan is complete, the install program asks if you want to 'Configure Additional SCSI adapters', hit 'S' to select this. It then displays a list of adapters with the last line highlighted reading: 'Other (Requires disk provided by a hardware manufacturer)'. This is the setup floppy created above. Hit Enter to select other, the program prompts to insert the floppy, do so and hit Enter again. The install program then reads the slcd32.sys device driver from the floppy, installs it, finds the CDU31A/CDU33A drive and uses it to install the operating system. The install program also makes all of the necessary registry entries automatically. For this to work the CDU31A/CDU33A host adapter MUST be set for IRQ 5. NOTE, THIS IS A CHANGE FROM THE PREVIOUS BETA. PREVIOUSLY THE DRIVER USED IRQ 3. If the host adapter jumpers are later changed the registry must be manually edited using REGEDT32. Adding support for CDU31A/CDU33A to a pre-existing NT system ------------------------------------------------------------ Within Windows NT under the window 'main', 'Windows NT Setup' select 'Options', then 'Add/Remove SCSI Adapters'. Then click on the 'Add' button. In the window 'Select SCSI Adapter Option', scroll the 'Adapter' selection down to 'Other (Requires a disk from a hardware manufacturer)'. Click on this option and when prompted insert the floppy with the Sony files. The system copies the device driver from the floppy and makes all the necessary registry entries automatically. These entries assume an IRQ of 5. If the host adapter jumpers are later changed or if you are using an IRQ other than 5, the registry must be manually edited using REGEDT32. NOTE, THIS IS A CHANGE FROM THE PREVIOUS BETA. PREVIOUSLY THE DRIVER USED IRQ 3. CDU31A/CDU33A Unique registry entry data ---------------------------------------- In addition to the normal mini-port stuff, the registry entry allows specifying a base port address for the host adapter and which IRQ it's set for. If the base port address is specified, then the driver does not do its search for a host adapter and drives. Specifically, under the entry for Slcd32 add a key for 'Parameters', and under this add the key 'Device0'. This is for the first host adapter. Under this add a value named 'DriverParameter' of type REG_SZ. This is a string where you can specify the parameters. Entries are of the form: 'name = value' where allowable names are: 'base' and 'irq'. Upper or lowercase is not important and all values are hex. Entries are separated by spaces. For example to specify the defaults of the adapter jumpers and driver use the value: base = 340 irq = 5 The driver defaults to irq 5 and will search for a host adapter and drives if no entry is made. The hex port addresses searched are: 340, 230, 330, 350, 360, 250, 348, and 320 The base address and irq must match the host adapter jumper settings. Note that the Sony host adapter model CDB-334 currently does NOT come shipped with an irq selected since interrupts are not used with the DOS device driver. For installation, my registry entry is: HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services Slcd32 -> Type: REG_DWORD: 0x1 Start: REG_DWORD: 0x0 Group: REG_SZ: SCSI miniport ErrorControl: REG_DWORD: 0x1 Parameters Device0 -> DriverParameter: REG_SZ: base = 340 irq = 5 Jumper settings for the Sony CDB-334 host adapter.

If the tray is being opened, the computer suspends to start up. And the computer resumes to start up after the tray is inserted.
